* Stop verifying hasPHIKill() flags.Jakob Stoklund Olesen2011-09-151-11/+1
| | | | | | | | | | There is only one legitimate use remaining, in addIntervalsForSpills(). All other calls to hasPHIKill() are only used to update PHIKill flags. The addIntervalsForSpills() function is part of the old spilling framework, only used by linearscan. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139783 91177308-0d34-0410-b5e6-96231b3b80d8
* RemoveCopyByCommutingDef doesn't need hasPHIKill().Jakob Stoklund Olesen2011-09-151-8/+8
| | | | | | | | | | | Instead, let HasOtherReachingDefs() test for defs in B that overlap any phi-defs in A as well. This test is slightly different, but almost identical. A perfectly precise test would only check those phi-defs in A that are reachable from AValNo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139782 91177308-0d34-0410-b5e6-96231b3b80d8
* It is safe to remat a value killed by phis.Jakob Stoklund Olesen2011-09-151-3/+1
| | | | | | | | | | | | | The source live range is recomputed using shrinkToUses() which does handle phis correctly. The hasPHIKill() condition was relevant in the old days when ReMaterializeTrivialDef() tried to recompute the live range itself. The shrinkToUses() function will mark the original def as dead when no more uses and phi kills remain. It is then removed by runOnMachineFunction(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139781 91177308-0d34-0410-b5e6-96231b3b80d8
* Leave hasPHIKill flags alone in LiveInterval::RenumberValues.Jakob Stoklund Olesen2011-09-151-21/+0
| | | | | | | | | | | It is conservatively correct to keep the hasPHIKill flags, even after deleting PHI-defs. The calculation can be very expensive after taildup has created a quadratic number of indirectbr edges in the CFG, and the hasPHIKill flag isn't used for anything after RenumberValues(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139780 91177308-0d34-0410-b5e6-96231b3b80d8

* Hoist back-copies to the least busy dominator.Jakob Stoklund Olesen2011-09-142-2/+66
| | | | | | | | | | | | | | | | When a back-copy is hoisted to the nearest common dominator, keep looking up the dominator tree for a less loopy dominator, and place the back-copy there instead. Don't do this when a single existing back-copy dominates all the others. Assume the client knows what he is doing, and keep the dominating back-copy. This prevents us from hoisting back-copies into loops in most cases. If a value is defined in a loop with multiple exits, we may still hoist back-copies into that loop. That is the speed/size tradeoff. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139698 91177308-0d34-0410-b5e6-96231b3b80d8

* One more patch towards JIT support for Mips.Bruno Cardoso Lopes2011-09-146-130/+287
| | | | | | | | | | | | | | - Add TSFlags for the instruction formats. The idea here is to use as much encoding as possible from getBinaryCodeForInstr, and having TSFLags formats for that would make it easier to encode most part of the instructions (since Mips encodings are pretty straightforward) - Improve the mips mechanism for compilation callback - Add Mips specific code for invalidating the instruction cache - Next patch will address wrong tablegen encoding Commit msg added by my own but the patch is from Sasa Stankovic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139688 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | alignment check for 256-bit classes more strict. There're no testcases but we catch more folding cases for AVX while running single and multi sources in the llvm testsuite. Since some 128-bit AVX instructions have different number of operands than their SSE counterparts, they are placed in different tables. 256-bit AVX instructions should also be added in the table soon.
